Karol Beffa has led an eclectic life, from starting as a child actor to securing several degrees outside the musical world to establishing a career as a composer and pianist. Beffa's growing catalog spans many genres, from solo instrumental and chamber ensembles of varying sizes to larger-scale works, such as operas, symphonic music, and ballet. He has also returned to acting and is an author, which includes a series of books that see its main characters, Sol & Rémi, meet famous composers. As of 2023, the duo had met Ravel, Beethoven, and Satie. That year, Beffa's work Tabula rasa, for violin and piano, was heard on the album Change by Elsa de Lacerda and Pierre Solot.
